I agree with the previous discussion about wheat. I am disappointed that the zone cereal contains wheat. So I guess that's out of the picture.

My wife and I have gone mostly grain-free; however, when I travel on business, about twice per year, i do order the cereal.
It holds me fairly well. And I only use 1/2 cup, 2 blocks, with additional food. I think, also, as a granola type snack it could be useful in a pinch.

John... The Zone Cereal is a great go to snack. I use it as a base for a trial mix when I hike, kayake and golf. I also love it for breakfast. it is a great start to the day.

Not to be contrarian, but I think some of the reaction to wheat and glutens is a bit overblown. Yes, if you have celiac disease, avoid glutens. But by the same token, if you have a peanut allergy or allergic to shellfish, then you shouldn't eat those foods either, that doesn't mean they are unhealthy foods that are bad for other people. Listen, I like a lot of what the paleo-diet crowd has to say... BUT, I think they take it a little far. The reality is that most people can handle glutens and wheat in moderation. Additionally, while there is a lot to like about Paleo-style diets, some of the science they use to promote it is a little sketchy. We know that our bodies can fairly rapidly adapt to new foods. This is why there are varying degrees of lactose intolerance among different groups of people. This is why certain groups are very resistant to alcoholism and others are not. Evolution at work over only a few thousand years! Now, I tend to limit my intake of glutens, but I most certainly don't avoid them altogether. It isn't like glutens are the equivalent of trans-fats. Glutens in moderation, in the absence of any allergies, are fine. The key, as always, is moderation.

I really can't say either way, but I tend to avoid wheat, as it is a major contributer to kicking my butt OOZ.

I am surprised that the Zone cereal was manufactured with wheat, as wheat is an unfavorable carbohydrate.

My two cents, while I've avoided grains for he most part of my 17 years in the Zone, I've got to say I certainly haven't for the past 2 1/2 years while I've been basing my meals on Zone foods (they contain significant amounts of wheat). During the past 2 years I'm happy to say I've had the lowest lipid levels of my entire adult life and I've been able to stay in the Zone and suppress appetite far better than in the past.

Contributing another 2 cents worth,
My opinion only, but if the Zone were to come up with a non-gluten/wheat product, they could market their products to a larger number of folks. I have always said that the Zone Diet is an excellent diet to follow for those who are gluten intolerant, and have talked it up with some of the people I know who are gluten intolerant. If they could just come up with more options for those folks who might just be looking at this diet as a good diet to follow for their condition, then perhaps there would be a larger market for the products that they sell.

And, of course, I also feel that their products need to be made available in stores, and not just online. The Zone cereal is the only product that is available, and even at that, is difficult to find.

(on a side note, I have a good friend who has Celiac, and she and I always seem to get along just fine when we go somewhere together because we eat in a similar fashion. She is not necessarily following the Zone lifestyle, but she is able to easily come to my house for dinner because I rarely serve foods with gluten)
